Detailed Implementation
[0025] Please see Figures 1-4 In this embodiment of the present invention, an integrated crusher with a pre-screening device includes an outer fixed frame 1; the outer fixed frame 1 has a fixed frame through groove 2 inside, and the inner side wall of the fixed frame through groove 2 has a plurality of upper fixed frame moving grooves 3. An upper conveyor belt fixed frame 4 is slidably connected to the outer side of the upper fixed frame moving groove 3, an upper conveyor belt 5 is rotatably connected inside the upper conveyor belt fixed frame 4, and a screen 6 is fixedly connected inside the upper conveyor belt 5; a connecting rod 7 is fixedly connected to one side of the upper conveyor belt fixed frame 4, a vibration motor 8 is fixedly connected to one side of the connecting rod 7, and an upper support frame 9 is provided below the vibration motor 8; a crushing box body 10 is fixedly connected to the lower right end of the outer fixed frame 1, a side support frame 11 is fixedly connected to the front right side of the crushing box body 10, and a drive motor 12 is fixedly connected to the middle of the side support frame 11; a main rotating shaft 13 is fixedly connected to the output end of the drive motor 12, a front sprocket 14 is fixedly connected to the outer side of the main rotating shaft 13, and a front crushing roller 1 is fixedly connected to one side of the main rotating shaft 13. 5; A chain 16 is rotatably connected to the outer side of the front sprocket 14, and a rear sprocket 17 is rotatably connected to the rear side of the chain 16. A rotating shaft 18 is fixedly connected to the middle of the rear sprocket 17, and a rear crushing roller 19 is fixedly connected to one side of the rotating shaft 18; Several slots 20 are cut on the left and right sides of the outer surface of the crushing box body 10, and detachable inspection plates 21 are movably connected to the front and rear sides of the outer surface of the crushing box body 10; A viewing window 22 is cut on the outer surface of the detachable inspection plate 21. The detachable inspection plate 21 has several locking blocks 23 on its left and right sides; several lower support rods 24 are fixedly connected to the lower side of the outer fixed frame 1, a side baffle 25 is fixedly connected to one side of the lower support rod 24, and a lower conveyor belt fixing frame 26 is fixedly connected to the lower side of the side baffle 25; a lower conveyor belt 27 is rotatably connected inside the lower conveyor belt fixing frame 26, a connecting plate 28 is fixedly connected to the left side of the lower conveyor belt fixing frame 26, and several fixed bases 29 are fixedly connected to the front and rear ends of the lower side of the lower conveyor belt fixing frame 26.
[0026] The working principle of this utility model is as follows: In use, the device is first placed in a suitable position using the fixed base 29. Then, the material to be screened and crushed is placed on the upper conveyor belt 5. The upper conveyor belt 5 is then started, causing the material to move to the right. During this movement, the vibration motor 8 is started, causing the connecting rod 7 to vibrate up and down. The connecting rod 7 then causes the upper conveyor belt fixing frame 4 to vibrate up and down along the upper fixing frame moving groove 3. This causes the upper conveyor belt 5 and the material on it to vibrate up and down. Material smaller than the mesh size of the screen 6 will fall to the lower side and onto the lower conveyor belt 27. The lower conveyor belt 27 is then started, causing the fallen material to move to the left. The material is then collected after screening. Material larger than the mesh size of screen 6 moves to the right along the upper conveyor belt 5 until it falls into the crushing chamber 10. This completes the screening process. Screen 6 allows for the screening of materials that need crushing, separating materials that already meet the finished product particle size requirements beforehand, eliminating the need for further crushing. This reduces unnecessary dwell time and processing time of qualified materials within the crusher, speeding up the entire crushing process and enabling the processing of more material per unit time, thus improving overall efficiency. Furthermore, the crushing chamber 10 can then focus on processing larger particles that require further crushing. To prevent the crushing chamber body 10 from being overloaded by a large amount of qualified fine material, ensuring it always operates in a relatively reasonable and efficient working state, reducing downtime and maintenance due to equipment overload, further guaranteeing production continuity and improving efficiency, the drive motor 12 is then started. The drive motor 12 drives the main rotating shaft 13 and the front crushing roller 15 to rotate. At the same time, the main rotating shaft 13 drives the front sprocket 14 to rotate, the front sprocket 14 drives the chain 16 to rotate, and the chain 16 drives the rear sprocket 17, the driven rotating shaft 18, and the rear crushing roller 19 to rotate. Then, larger materials entering the crushing chamber body 10 can be crushed. After crushing, the crushed material falls onto the lower conveyor belt 27, and then the lower conveyor belt 27... This will cause the crushed material to move to the left, and then the crushed material can be collected. When the front crushing roller 15 and the rear crushing roller 19 are damaged and need maintenance or repair, simply press the locking block 23 until it is completely separated from the locking groove 20. At this time, the fixation of the detachable maintenance plate 21 is released, and then the detachable maintenance plate 21 can be removed from the crushing box body 10 for maintenance or repair of the front crushing roller 15 and the rear crushing roller 19. By removing the detachable maintenance plate 21, the front crushing roller 15 and the rear crushing roller 19 can be maintained or repaired conveniently and quickly. This not only saves a lot of preparation time and manpower, but also enables timely response to equipment maintenance needs, reduces equipment downtime waiting for maintenance, and improves the continuity of overall work.Furthermore, it eliminates the need for large-scale disassembly and transportation; workers only need to disassemble and install the removable maintenance plate 21, a relatively easy task. This significantly reduces labor intensity and makes maintenance easier, especially during frequent routine equipment checks and minor fault repairs. It also allows for direct operation on the areas containing the front crushing roller 15 and rear crushing roller 19, enabling precise maintenance tasks such as cleaning, lubrication, and replacement of worn parts. This more targeted approach ensures the quality and effectiveness of maintenance, helps maintain stable crushing performance of the front and rear crushing rollers 15, and extends the equipment's lifespan.
